For the preamp and pickup you should be using 25k pots. 500k pots are more normally used for passive humbuckers.

 

I actually have no idea what effect 500k pots would have but I'm sure that someone will be along to explain.

 

the Aguilar and EMG websites both specify 25k pots

The 500k pot value is the problem. The EMG specs recommend 25k vol and tone pots for this pickup so I'd try a dual MN25K pot for the blend.

Just an update to this, I got a 25k MN pot and it works perfectly now. Thanks to Delberthot and ikay for steering me in the in the right direction!

Loading affects the pickup response. Active mixing does not load pickups. This is especially feasible with hi-Z pickups.

 

Buffered output is very stiff, therefore the blend can be a simple pot. If the 250k is too big, you can solder metal film resistors in parallel with the individual tracks. Then the pot tracks look smaller in resistance.

 

Few alternatives:

100k resistors in parallel - 71k tracks

68k - 53k

56k - 45k7

47k - 39k5

33k - 29k

27k - 24k

And so on.

 

EMG has 10k output impedance, 27k resistors would be a nice match.

Thank you for the alternate suggestions itu, I ended up getting a lower resistance pot since it seemed less fiddly than wiring up resistors and I definitely didn't want to dip in for the active blend due to the price. £4 for 3 pots off ebay was a lot more enticing than $80 + shipping from EMG or the Noll.

I guess that's a good place to start, just need to get hold of one of those pots then, thanks!

What is slightly different with your pickups is that they are lo-Z, compared to most others (which are high impedance, "passive"). The blend pot is the first in signal path after the pickups.

 

You can use a hi-Z pot (250k MN or 500k MN), but the feasible area of the pot tracks will be short. From this point of view two volumes would work. You can also opt for the "active" mixing via the battery operated Noll Mixpot.

Vol/Vol would be easier but Ideally I want the blend for quicker dialing, I guess that would be what I'd go for if I can't get the blend to work. What makes you recommend active mixing? I saw the EMG active pot but it seems excessive and it claimed to solve a problem I don't have.

My understanding was that 25k was for Volume and Tone, and that blend didn't matter as much? If I did need 25k that would explain the issue though.

They're all the same really. The blend controls,that I've had experience of, just act as an on/off switch.

 

There may be a smidgeon of a blend, a mm either side of the centre but in my experience they give you bridge pickup on full, neck pickup on full, or both on full together.

That's the thing, the blends I've had up until this point are nothing like this. The blend I have in my Warwick works perfectly and the blend I have in my Ibanez SR isn't perfect but it's a lot better than this one, so that's why I'm confused. Granted, they both have passive pickups on an active circuit rather than both active

I've very recently come into a problem I didn't know existed when I got hold of a used bass in a trade. The blend pot doesn't blend, it functions more like an on/off switch where the extra pickup will only be added in when getting very close to the centre notch, and for 90% of the travel, you just hear one pickup. I looked up the issue and I've seen a couple of similar problems but they reference specific things that don't apply to my case so I'm wondering how the differences affect me.

I have an OBP-2 loaded bass (the bass was originally shipped with a different preamp that was swapped out) with dual EMG 35DC active pickups and the pot in question is a MN500K, I tried ungrounding the blend as I've seen a few forum users suggest, but it made no difference. Is my next step to just try a lower pot value and seeing what difference that makes? From what I understand the default configuration of the OBP-2 is to use Vol Vol rather than Vol Blend so I'm wondering if something may have been overlooked in the initial install also.

Any thoughts or perspective are appreciated!

Cheers Paris. Nice to meet you. Sorry it was a flying visit but we had a long trip back 😁

You too Kev! Totally get it, hope you're getting on well with the bass.

Love the Streamer. Swap for a Vampyre 5?

Thanks for the offer Jimmy, the Vampyre isn't to my taste though I'm afraid. Couldn't tempt you to buy?

Aerodyne traded to kevham! Warwick Rockbass still available

Hello fellow lefties, bass players, and misfits!

Long time lurker here gauging interest on possible trades for my lovely '07-08 Fender AJB (MIJ T04 serial) currently equipped with Rotosound Roto Bass 45-105. This bass is stock as far as I know, however I am not the first owner so I can't say for sure if anything has been changed or if it has been gigged. BUT, I can tell you that it works perfectly and it's a fine example of a sleek, modern looking vintage specced bass. The bass is 15 years old, and it has been played. Usual wear and tear aside from some chips in the P pickup treble poles, but it's in pretty good nick considering so I'd want roughly £850 trade value from it. Willing to take or put in cash to make up the balance for an uneven trade. If you simply MUST have this, I'll consider cash offers in the event I don't get much interest. Gallery can be found here. I tried my best to capture dings, but most of them aren't noticeable, especially to a camera trying to photograph a shiny black instrument. Traded!

As many of you know, these are quite hard to come by since they were made to be sold on the domestic market in Japan so they don't pop up often. I've had it for a few years but it doesn't really get played so I'm looking to see what people have to offer! I would ideally like to do an in person trade, either in Cheshire East or Greater Manchester, but I know how rare we are so I'll consider trades case by case. I'm mainly looking for one of the following in 4 or 5 string (bonus points for matching headstock) but I'm open to trade offers, however I'm mostly interested in MM humbucker equipped basses;

Musicman Stingray

Musicman Bongo

Musicman Sterling

Ibanez ATK

Warwick $$

Warwick Thumb (5 string)

Sandberg California TM or TM2

Alternatively;

If you have a cool £250 burning a hole in your wallet I'm offering my '12 Warwick Rockbass Streamer Standard 5 in Nirvana Black currently strung with (old) D'Addario Prosteels 45-145 to all you fine individuals at BassChat. This was my learner bass, bought new back in '12/13 (after they started putting Rockbass on the truss rod cover rather than the headstock) so it has seen me going off to university and lugging it around, certainly no case queen. This is a fine example of a simple and cheap, but reliable instrument that won't let you down. Gallery can be found here.

Thanks for looking, and happy slapping!

Paris

I'd say Cliff Burton or Geddy Lee. Both brilliant players who were instrumental in laying the groundwork for all the music I know and love today. Cliff is who I would want to be like but I have to admire Geddy for what he does. Honourable mention would be Greg from InMe, great band who don't get the recognition they deserve.

Can't help but be drawn to that swing bass tone haha
